Photodermatosis
Photodermatosis (pronunciation: /ˌfoʊtoʊ.dɜːrˈmæ.toʊ.sɪs/) is a medical condition that refers to an abnormal skin reaction to sunlight, or more specifically to ultraviolet (UV) radiation.
Etymology
The term "Photodermatosis" is derived from three Greek words: "photo" meaning light, "derma" meaning skin, and "osis" meaning abnormal condition or disease.
Types of Photodermatosis
Photodermatosis can be categorized into several types, including:
- Polymorphic Light Eruption (PMLE)
- Solar Urticaria
- Drug-induced Photosensitivity
- Photoallergic Eruption
- Chronic Actinic Dermatitis (CAD)
- Actinic Prurigo
Symptoms
Common symptoms of photodermatosis include:
- Redness and swelling of the skin (erythema and edema)
- Itching or burning sensation (pruritus)
- Development of rash or bumps on the skin
- Dark patches on the skin (hyperpigmentation)
Causes
Photodermatosis is usually caused by an abnormal immune response to sunlight, particularly its ultraviolet (UV) component. Certain medications, skin care products, or other substances can also make the skin more sensitive to sunlight, leading to photodermatosis.
Treatment
Treatment for photodermatosis typically involves avoiding sun exposure, using sun-protective clothing and broad-spectrum sunscreens, and in some cases, taking medications to manage symptoms or underlying conditions.
